IMPROVEMENT IN CULTIVATORS.

Specification forming part of Letters Patent No. 180,354, dated July25,1876; application filed June 7, 1876. I

in the State of New Jersey, have invented certain new and usefulImprovements in Cultivators; and do hereby declare that the following isa full, clear, and exact description i thereof, reference being had tothe accompanying drawings, and to the letters of reference markedthereon, making a part of this specification.

The nature of my invention consists in the construction and 'arrangementof a cultivator, as will be hereinafter more fully set forth.

and use the same, I will now proceed to describe its construction andoperation, referring to the annexed drawing, in which- Figure l is aperspective view of my cultivator. Fig. 2 is a plan View of one set ofbeams. Fig. 3 is a vertical section through the line a: of Fig. 2. A

The frame of my cultivator is composed of two runners, A A, eachprovided with front and rear standards B B', and the correspondingstandards of the two runners ccnnected by front and rear cross-beams CC', as shown, this being a well-known frame, already patented to me.

The two beams 'C C' are connected by the tongue D. E E are the handles,fastened to the top of the rear beam C', and to the inner lsides of thefront standards B B. -On each side of this frame are two plow-beams, GG, the front ends of which are fastened to the ends of a clevis, H, saidends being in the form of straps a a, as shown, so as to be capable ofspringing slightly.

The clevis H is in front of the standard B, the straps a a straddlingthe same, and fastened thereto with the plow-beams on the inner sides ofthe straps, and their front ends immediately in rear of the standard, asshown in Fig. 2.

One of the plow-beams G is on the outer, and the other'on the inner,side of the rear standard B', and are fastened to a cross-bar,

ther apart,. as desired, the spring of the arms a of the clevis allowingof such adjustment.

The rear end of each beam G is slotted vertically, and in the same ispivoted the shank J, to the lower end of which the plow In order toenable others skilled in the artv 'towhich my invention appertains tomake K is secured. 'lhe shank J is perforated so that it can be adjustedup and down, as required, by simply changing the pin e in differentholes in the shank. To the under side of the beam G is fastened a metalbar, L, the rear end of which is forked, and the shank J is passedthrough said fork, with a wooden'pin, z', passed through the prongsbehind the shank, so that if the plow strikes a stone or otherobstruction said pin will break, and the plow turn backward, thuspreventing breakage of any of the parts.

In the rear standard B', on each side of the frame, is fastened an arm,M, which projects rearward, and has another arm, N, attached to itsunder side. The eXtreme rear-ends of both arms M and-N are forked, andin the upper one, M, is pivoted a perforated plowshank, J', with plow K'at its lower end, it being held by the wooden break-pin in the fork ofthe lower arm, N.

Having thus fully described my invention,y

what I claim as new, and desire to secure by Letters Patent, is-

1. The combination, with the beams G Gr and standard B, of the clevis H,secured to the standard, and having extended ends a a, forming springs,which are connected to the beams Gr G, substantially as and for thepurposes herein set forth.

2. The combination of the standards B B', the beams G G, connected tothe springs c a of the clevis, and the cross-bar I, provided with curvedslots w fr, and the adjusting bolts and nuts b'd, all substantially asand for the In testimony that I eiailn the foregoing I purposes hereinset forth. have hereunto set my hand this 17th day of 3. The combinationof the standard B ad- May, 1876. y
